Vanilla extract (2 teaspoons): Enhances the overall flavor with its warm, aromatic notes.
All-purpose flour (3 cups): The foundation that gives the cake its body and rise.
Baking powder (2 teaspoons): Works with baking soda to ensure a light, fluffy texture.
Baking soda (1 teaspoon): Helps the cake rise and prevents it from becoming dense.
Salt (1 teaspoon): Balances the sweetness and boosts the other flavors.

How to Make Bundt Coffee Cake with Cinnamon Sugar and Walnuts Recipe

Step 1: Prepare Your Pan and Cinnamon Sugar Mixture

Start by preheating your oven to 350 degrees Fahrenheit. Grease and flour a 10-inch Bundt pan to prevent the cake from sticking—this step makes removing your beautiful cake so much easier. In a small bowl, mix together ¾ cup of white sugar, the ground cinnamon, and the chopped walnuts. This mixture will become the irresistible filling that makes every bite special.

Step 2: Cream Butter and Sugar

Using a mixing bowl, beat the softened butter together with 2 cups of white sugar until the blend is light, fluffy, and pale in color. This process incorporates air, giving your cake a lovely lift and a tender crumb. It’s a satisfying step that sets the foundation for a cake that’s anything but ordinary.

Step 3: Add Eggs and Vanilla

Next, add the eggs one at a time, beating well after each addition to keep the batter smooth and creamy. Mix in the vanilla extract as the final flavor enhancer here—it brings such warmth and depth that makes the Bundt Coffee Cake with Cinnamon Sugar and Walnuts Recipe utterly enchanting.

Step 4: Combine Dry Ingredients and Sour Cream

In another bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. Incorporate this mixture alternately with the sour cream into the creamed butter and sugar bowl. This technique helps maintain the batter’s airiness while ensuring the sour cream evenly enriches the texture, making every forkful melt deliciously on your tongue.

Step 5: Layer Batter and Cinnamon Sugar in the Pan

Spoon about one-third of the batter into your prepared Bundt pan and spread it out evenly. Sprinkle a layer of one-third of the cinnamon sugar and walnut mixture over the batter. Repeat these layers two more times—you’ll create those eye-catching swirls packed with cinnamon sugar and crunchy nuts that define this recipe.

Step 6: Bake Until Golden and Done

Place the cake in the preheated oven and bake for 60 to 70 minutes, or until a toothpick inserted near the center comes out clean. The aroma will start to fill your kitchen, and that golden crust will signal the cake is ready. Let it cool in the pan for about 10 minutes before flipping it onto a wire rack to cool completely—this gives you perfect slices and a gorgeous presentation.

How to Serve Bundt Coffee Cake with Cinnamon Sugar and Walnuts Recipe

A Bundt cake with a golden brown outside and a yellow inside sits on a white plate. The cake is shaped in a ring with deep curves all around it. A slice is removed showing two visible layers inside: the main yellow cake and a swirled, darker cinnamon filling running through the middle. There are some crumb pieces and cinnamon powder scattered on the plate near the missing slice. The background is a white marbled texture, and there are blurred jars and a striped cloth in the back.

Garnishes

A simple dusting of powdered sugar can elevate your Bundt coffee cake instantly, giving it an elegant finish without overpowering the flavors. If you want to indulge further, a light glaze made of powdered sugar mixed with a splash of milk or cream drizzled over the top adds just the right amount of sweetness and shine.

Side Dishes

This Bundt Coffee Cake pairs beautifully with a hot cup of coffee or tea, making it a perfect companion for breakfast or afternoon tea time. Fresh fruit, like sliced strawberries or a handful of blueberries, adds a refreshing, juicy contrast that balances the cake’s richness.

Creative Ways to Present

For a festive touch, serve slices with a dollop of whipped cream and a sprinkle of extra chopped walnuts on top. You can also cut the cake into bite-sized squares for a charming dessert platter at brunches or gatherings. Its beautiful cinnamon swirl makes every slice a showstopper!

Make Ahead and Storage

Storing Leftovers

Once cooled, wrap your Bundt coffee cake tightly in plastic wrap or place it in an airtight container to maintain freshness. Stored at room temperature, it will stay delicious for up to three days, perfect for quick snacks or unexpected guests.

Freezing

If you want to extend the cake’s life or prepare ahead, wrap it securely in plastic wrap followed by aluminum foil and freeze. It keeps well for up to two months. When ready to enjoy, thaw overnight in the refrigerator, or at room temperature for a few hours before serving.

Reheating

Reheat individual slices in the microwave for about 15 seconds to revive that fresh-baked warmth, or pop the entire cake in a low oven (around 300°F) for 10-15 minutes. This will refresh the texture without drying it out, bringing back that soft, tender crumb we all love.

FAQs

Can I use a different type of nut in this Bundt Coffee Cake with Cinnamon Sugar and Walnuts Recipe?

Absolutely! While walnuts offer a wonderful texture and flavor, pecans or almonds can be great substitutes that also complement the cinnamon sugar beautifully. Just be sure to chop them roughly to maintain that satisfying crunch.

Is it necessary to use sour cream in this recipe?

Sour cream is key for moisture and a slight tang that balances the sweetness; however, you can substitute it with Greek yogurt or buttermilk if needed. Just keep the quantities the same for best results.

Can I make this cake dairy-free?

Yes, you can! Use dairy-free butter substitutes and a plant-based sour cream or yogurt alternative. These swaps will slightly alter the texture but still yield a tasty coffee cake.

How do I know when the Bundt coffee cake is fully baked?

The best test is inserting a toothpick near the center of the cake; if it comes out clean or with just a few crumbs attached, your cake is perfectly baked. Avoid opening the oven too early to prevent it from collapsing.

Can I halve this Bundt Coffee Cake with Cinnamon Sugar and Walnuts Recipe?

You can, but keep in mind that baking times will change. Using a smaller pan will reduce baking time significantly, so start checking for doneness around 35 to 40 minutes to avoid overbaking.
